What is Surface Condenser?
Surface condenser has a great advantage over jet condensers, as the condensate does not mix up with cooling water. This condenser, whole condensate can be reused in the boiler. The fig show that a longitudinal section of surface condenser. It consists of horizontal cast iron cylindrical vessel packed with tubes through which cooling water flow. The bottom of the condenser are cut off by vertical perforated plates through which water tubes are fixed.
This is done in such a manner that the leakage of water into the water condensing space is prevented or avoided.
The water tubes pass horizontally through the main condensing space for steam. The steam enters at top exhaust steam inlet and is forced to flow downwards over the tubes due to suction of extraction pump at the bottom. The cooling water flows in one direction through the lower half of tubes and returns in opposite direction through the upper half.
This type of condensers are used in land installation.
Types of Surface condenser
1) Down flow surface condenser.
2) Central flow surface condenser.
3) Regenerative surface condenser.
4) Evaporative condenser.
Advantages
1) Plant efficiency is more.
2) High vacuum is created.
3) Free from harmful impurities.
Disadvantages
1) More space required
2) Capital cost is high.
3) Maintenance cost is high.
So in this article we discussed What is Surface Condenser? it's Types and Advantages, Disadvantages hope this information is useful for your best understanding.
